Compaq persario CQ50-211NR

\015 Screen wont turn on .the hard drive runs but no screen\015

Answers :

I have the same problem. Right now, I suspect an overheated GPU. When I try toboot, I get normal led displays (power, hardrive activity) and the dvd drive spins. However, I get no display. The backlight comes on, but no display. Also, no video out to vga or hdmi devices. After testing the ram, I did some more research.\015\012\015\012I found the following results:\015\012*HP (aka compaq) devices are notorious for overheating.\015\012*low grade solder used on the gpu (less lead content = lower melthing temps)\015\012*poor heat distribution engineering on the gpu\015\012\015\012What is happening is that the computer is overheating, melting the on board gpu chip and breaking its circuitry.\015\012\015\012One fix that I've seen in other HPs is to reheat the gpu to melt the solder and hope for the best. See this link for a video demo (http://www.youtube.com/watch?v=ctHTF3oNdxI)\015\012\015\012I almost went through with this procedure for our laptop model, but didn't go through with it because of the surface mounted micro circuitry near the gpu. \015\012\015\012Best of luck, I'll let you know if I actually go through with the procedure and what happens~

OkwHen you power up the copmputer press F8 key then enter in enable vga mode then go to dispaly property and change screen resolution to 1024*768 then apoply and ok.

On my compaq persario cq50, the touchpad scroll randomly stops working for hours at a time, ad I have to manually pull down the screen. It's harddrive has already blown once, and I had it replaced, but this problem has been going on with both of the hard drives. Can I fix this?

The place where you insert it should be somewhere around the left side of your laptop. It looks like a narrow, rectagular strip and make sure your adapter fits in the slot.\015\012\015\012Hope this helps, and have a nice day! ^_^ ...
